I've checked the Steam directory and the user's AppData directory: If there's an error log for Decoda I can't find it.

This is the kind of thing that goes on behind close doors on normal game releases, where they are optimizing it right up until the end. You guys are just getting to play with a version of the game that normally only the developers see.

If I try to open a .deproj I get the same side-by-side configuration error.
